Answer:

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

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:

  • <u>Study time for english</u> = 1/5.
  • <u>Study time for science</u> = 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.

Is 16.45 greater than 16.454
Ivenika [448]
No. 16.454 has an extra number at the end. If the 4 at the end of 16.454 was a 0 then it wouldn't matter and they would be equal.
