When we multiply a fraction by 1 we get?

So I can multiply any number by 1 and get the same value and anything multiplied by 1 is simply that value. The same thing works when I divide by 1 – I get the same number.

Should we take LCM for multiplication of fractions?

Answer: During addition we use LCM as the denominator should be same for adding or subtracting a fraction. But during multiplication we do not take LCM as multiplication is the repeated addition, so there is no need to make the denominator same or equal to other fraction’s denominator.

What is the effect of multiplying by a value less than 1?

When multiplying a number by a decimal less than one, the product will be smaller than the number being multiplied. This is because we are finding a fractional amount of a quantity. For example, 0.1 x 0.8 = 0.08, because the question is asking us to find one tenth of eight tenths.

Why don’t we need common denominators when multiplying fractions?

It doesn’t matter if we are scaling an integer as in the previous examples, or if we are scaling a fraction, or if we are scaling something else altogether (e.g. ), the process is the same. Thus, having similar denominators when multiplying fractions is unnecessary.

When we multiply a fraction by 1 we get the same fraction True or false?

We know from multiplication and division that when you multiply or divide a number by 1 you get the same number. We also know that when you have the same numerator and denominator in a fraction, it always equals 1.

Will multiplying a fraction by a whole number ever result in a number less than 1?

1 Expert Answer If you multiply any whole number by a fraction, you will get a smaller number! Here is an example of this: 1/2 * 4 = 2.

Why when you multiply fractions do they get smaller?

When you multiply by a fraction, you are finding that fraction, or portion, of the original whole. Assuming that you’re dealing with “proper” fractions (which are smaller than 1), then you must end up with a smaller value, because you’re taking only part of the original value.

Why does multiplying by a fraction greater than 1 result in a product greater than the original number?

When a number is multiplied by a fraction equivalent to 1, the product is equal to the number. When a positive whole number is multiplied by a fraction greater than 1, the product is greater than the whole number.

Why do we multiply fractions the way we do?

In a fraction, denominator represents the total number of parts a whole is made into and the numerator represents the number of parts chosen. A fraction is multiplied by another fraction means the first fraction is further divided into smaller parts and these smaller parts are chosen.

How to find LCM and HCF of two fractions?

Formula to find the LCM of two fractions is: L.C.M =. Step 1: If the two fractions are : and. Step 2: LCM of two numbers is the lowest/smallest number which is a multiple of both. HCF of two numbers is the largest/maximum whole number which is a factor of both. Step 3: Let’s learn it using an example:

What is the difference between LCM and a common multiple?

A common multiple is a number which is a multiple of two or more numbers. LCM denotes the least common factor or multiple of any two or more given integers. For example, L.C.M of 16 and 20 will be 2 x 2 x 2 x 2 x 5 = 80, where 80 is the smallest common multiple for numbers 16 and 20.

How do you find the LCM of a given number?

There are three major methods to find the LCM of numbers, such as: Listing the multiples of the given numbers, prime factorisation of numbers and by division method. What is the relation between HCF and LCM? LCM and HCF are related by the formula: LCM (a,b) = axb/HCF (a,b)

What is the prime factorization method of finding LCM?

Prime Factorization Method of Finding LCM. 1 Step 1: To first list the prime factors of each number. 2 Step 2: Next multiply each factor the maximum number of times it occurs in either number. If the same factor occurs more than once in both numbers,
