Question

What is the value of 3/5 + 5/7 * 8/12 8/7 8/35 46/35​

Answer 1

Step-by-step explanation:

FIRST WE WILL FIND LCM OF 5, 7, 12 & 35 TO DO THE DENOMINATOR EQUAL.

LCM OF 5, 7, 12 & 35 = 5 × 7 × 2 × 2 × 3

= 420.

To make the denominators of all fractions same we will multiply them by a specific number which will give 420.

3/5 × 84/84 = 252/420

5/7 × 60/60 = 300/420

8/12 × 35/35 = 280/420

8/7 × 60/60 = 480/420

8/35 × 12/12 = 96/420

46/35 × 12/12 = 552/420.

So,

3/5 + 5/7 8/12 8/78/35 46/35

=

252/420 ( + 300/420 × 280/420 × 480/420 × 96/420 × 552/420 )

=

252/420 + 2086560000/12762815625

=

( 0.6 + 0.163 ) = approximate....

=
