Answer:

1 9/20 m.

Step-by-step explanation:

Subtract 2 1/5 and 3/4 and the answer is 1 9/20

Step-by-step explanation:

first make the mixed fraction into improper fraction by making 2 1/5 into 11/5 from the process of multiplying the remainder to the denominator then added to the numerators value ,after changing the first fraction we will subtract the both fraction given in the order of the question , after you write 2 1/5 - 3/4 into 11/5 - 3/4 the process subtracting fractions is by multplying the denominator to the denominator and it will be written down as the denominator of unknown difference of the both then multiply the first numerator to the second fractions denominator and subtract it to the product of the first fractions denominator to the second fractions numerator and you will get the difference and renamed it to be the numerator of this phase ,after subtracting it your answer should be in improper fraction then changing it to mixed number (if wanted) by dividing the numerator to the denominator the quotient will be your whole number(first number) and the denominator will remain the same but the remaining remainder will be your numerator.

SOLUTION:

> 2 1/5 - 3/4

> 11/5 - 3/4

> 44 - 15/20

> 29/20

> 20÷29

> 1.9

> 1 9/20
