Answer:

2 Hours

Step-by-step explanation:

4/7 of an hour = 34.3 minutes.

34.3 minutes per 2/7

4/7 = 68.6 OR 1 hour 8 minutes.

6/7 = 102.9 OR 1 hour 42 minutes.

Then add half of 34.3 (17.15)

7/7 = 120.05. = 2 hours 0.5 seconds.

Simplify the expression. -5/8(-3/8-1/4) ​
prisoha [69]

Answer:

25/64

Step-by-step explanation:

To get this answer, first you need to use the distributive property:

(-3/8)(-5/8) - (1/4)(-5/8)

Next, multiply:

15/64 - (-5/32)

Change the negative signs into a positive sign:

15/64 + 5/32

Multiply 5/32 by 2 on both top and bottom:

15/64 + (5)(2)/(32)(2)

You will then get:

15/64 + 10/64

Now, add the numerators. You will get:

25/64

This is your answer. I hope it helped!
