Question

which of the following fraction is the greatest? 3/5,3/4,2/7,1/2​

Answer 1

Answer:

3/4 is greatest

Step-by-step explanation:

Fractions are given as

3/5, 3/4, 2/7 and 1/2

In order to find which of the fraction is greatest, make the denominator equal and then arrange in ascending order

First, to make the denominator common, find the LCM (5, 4, 7 and 2)

LCM (5, 4, 7 and 2) = 5 × 4 × 7 = 140

Thus, we get

3/5 = (3 × 28)/(5 × 28) = 84/140

3/4 = (3 × 35)/(4 × 35) = 105/140

2/7 = (2 × 20)/(7 × 20) = 40/140

1/2 = (1 × 70)/(2 × 70) = 70/140

Now, arranging in the ascending order of numerator, we get

40/140, 70/140, 84/140 and 105/140

Thus, greatest fraction is 105/140 = 3/4

Answer 2
