Question

Simplify the following 1/3+(-3/4)+7/8​

Answer 1

Answer:

1/3+(-3/4)+(7/8)

first open the brakes

1/3-3/4+7/8

take the L.C.M

the L.C.M is 24

8/3×8 + 3×6/4×6+ 7×3/8×3

8/24+18/24+21/24

47/24

Answer 2

Given: 1/3, (-3/4), 7/8​

To find: Sum of the given numbers.

Solution:

• Fractions cannot be simplified if their denominators are different.
• In order to find the sum of the given fractions, the denominators of them are to be made equal using L.C.M..
• The L.C.M. of the denominators is 24.
• So, these fraction are converted into equivalent fractions having their denominator as 24.

        $\frac{1}{3} * \frac{8}{8} = \frac{8}{24}$

       $- \frac{3}{4} * \frac{6}{6} = - \frac{18}{24}$

        $\frac{7}{8} * \frac{3}{3} = \frac{21}{24}$

• Now, to simplify further, these equivalent fraction are added,

        $\frac{8 - 18 + 21}{24} = \frac{11}{24}$

Therefore, on simplyfying the answer is 11/24.
