3. First, turn the fractions into improper fractions
11/8 + 11/4
Since we can't divide 11 by 2 to make the denominator of the first fraction 2, let's multiply both sides of the second fraction by 2 instead.
11/8 + 11*2/4*2 = 11/8 + 22/8
<u>33/8, or 4 1/8</u>
(I already answered numbers 4 and 6 in a previous question you asked)
5. 1 1/2 + 2 3/4
Obviously, we'll start by converting the fraction into improper fractions.
3/2 + 11/4
Multiply both sides of the first fraction by 2
3*2/2*2 + 11/4 = 6/4 + 11/4 = 17/4
<u>17/4, or 4 1/4</u>
Answer:
40 60 40 60 40 60 40 60 40
1. 2. 3. 4. 5. 6. 7. 8. 9.
so the answer is 9 hours
Answer:
1/2
Step-by-step explanation:
Depth of the bathtub = 18 inches
Time taken to fill 3 inches of the bathtub = 2 minutes
Then
The amount of depth needed to fill with water = (18-3) inches
= 15 inches
Time required to fill 15 inches of the bathtub = (15*2)/3 minutes
= 30/3 minutes
= 10 minutes
So John is correct in thinking that it will take 10 more minutes for the water to reach the top of the tub if he continues at the same rate.
Hope this helps!
