Question

Simplify:- 7/2 + 3/4 -4/5

Answer 1

Answer:

69/20

Step by step explanation:

First we have to take Lcm of 2,4 and 5. ,

2/ 2,4,5

2/ 1,2,5

5/ 1,1,5

/ 1,1,1

L.C.M = 2×2×5

L.C.M = 20

And, then

we divide 20÷2=10×7=70/20

Now, we do same with the both fractions :

= 20÷4=5×3=15/20

= 20÷5=4×4=16/20

Now. the denominator of all fractions is same .

Now, we solve the problem.

= 70+15-16 = 85-16 = 69

20. 20. 20

= 69. Ans.

20
