Question

Divide the sum of-3by10 and 6by25 their difference

Answer 1

Answer:

Step-by-step explanation:

The sum of 3/10 and 6/25

3/10 + 6/25

= ( 5 × 3 + 2 × 6 ) / 50 ( ∵ The lcm of 10 and 25 is 50 )

= ( 15 + 12 ) / 50

= 27 / 50

The difference of 3/10 and 6/25

3/10 - 6/25

= ( 5 × 3 - 2 × 6 ) / 50

= ( 15 - 12 ) / 50

= 3 / 50

Now dividing the 27 / 50 and 3 / 50

27/50 ÷ 3/50

= 27/50 × 50/3

= 27/3

= 9 is the answer.
