1/1 - 1/70 as a fraction

Learn how to find what is 1/1 minus 1/70 in fraction form just in a few minutes. We have covered the easiest method to write 1/1 - 1/70 as a fraction and decimal.

Summary: 1/1 minus 1/70 = 69/70
Since both fractions have unequal denominators, 1/1 minus 1/70 is an unlike fractions subtraction. For subtracting unlike fractions, you have to first find the equivalent fractions for fraction 1/1 and fraction 1/70 in order to have the same denominators for both fractions. Therefore, you have to find the LCM of denominators 1 and 70. 70 is the LCM of 1 and 70. Multiplying the LCM 70 with the numerators and denominators of both fractions (1/1 x 70/70) - (1/70 x 70/70), and simplify further in order to have the common denominator. So the equivalent fraction for 1/1 is 70/70 and for 1/70 is 1/70. By simplifying this fraction subtraction 70/70 - 1/70, it becomes 69/70.

Pie Chart Representation: 1/1 - 1/70 = 69/70

The below workout with step by step calculation shows how to find what is the difference between two fractions by subtracting a fraction 1/70 from 1/1. For different, unequal or unlike denominators, use any one of the following methods to find the equivalent fraction for 1/1 minus 1/70.
1. LCM method
2. Cross multiplication method.

(1/1) - (1/70) using LCM Method:
What is 1/1 minus 1/70 as a fraction?

step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/1
Fraction B: 1/70

What to be found?
(1/1) - (1/70) = ?
Find what's the difference between 1/1 and 1/70.

step 2 Compare the denominators of fractions 1/1 and 1/70 to identify whether it is a like or unlike fraction subtraction. Since the denominators of given fractions 1/1 and 1/70 are not equal, it is said to be unlike fractions subtraction.

step 3For unlike fractions subtraction, find the LCM (least common multiple) of both denominators of fractions 1/1 and 1/70:
The LCM of 1 and 70 is 70.

step 4 Write the fractions 1/1 and 1/70 in the subtraction expression form and multiply LCM with all the numerators and denominators of both fractions.
= 1/1 - 1/70
= [(1 x 70)/(1 x 70)] - [(1 x 70)/(70 x 70)]

step 5 Simplify the expression to have common denominator:
= 70/70 - 1/70

step 6 Take the common values out and rewrite the above expression like the below:
= 1/70 x (70/1 - 1/1)
= 1/70 x (70 - 1)

step 7Simplify the above expression further:
= 1/70 x 69
= 69/70
1/1 - 1/70 = 69/70

Hence,
1/1 minus 1/70 as a fraction is 69/70.

1/1 - 1/70 using Cross Multiplication Method:
step 1 Observe the input parameters and what to be found:
Input:
Fraction A: 1/1
Fraction B: 1/70

What to be found?
(1/1)-(1/70) = ?
Find what's the difference between 1/1 and 1/70.

step 2 Find the product of numerator of Fraction A and denominator of Fraction B (1 x 70), find the product of numerator of Fraction B and denominator of Fraction A (1 x 1), and find the product of both denominators of Fraction A and Fraction B (1 x 70) and rewrite the equation as like the below:
= (1 x 70) - (1 x 1)/(1 x 70)

step 3 Simplify and rewrite the fraction:
= (70 - 1)/70
1/1 - 1/70 = 69/70

Hence,
1/1 minus 1/70 in fraction is 69/70
