Question

WILL MARK BRAINLIEST!!!

Answer 1

Answer:

Okay the question is a little unclear, but if he's only doing english, science and history the answer should be 17/40

Step-by-step explanation:

1/5=8/40

3/8=15/40

8/40+15/40=23/40

40/40-23/40=17/40

Answer 2

ANSWER:

• Study time for english = 1/5.
• Study time for science = 3/8.

We will first equate the denominator of the fractions.

So, 1/5 × 8/8 = 8/40

3/8 × 5/5 = 15/40

• 8/40 + 18/40 = 23/40

Total time = 40/40 = 1.

So for history work, he used

• 40/40 - 23/40
• 17/40.
