20
U have to divide it by 3 the ratio is 1:3
57 miles about I'm not positive but I think this is right
Ok so
Q.1=B
Q.2=B
Q.3(a)=(d-45)+m+65
(b)=d+m+20
Answer:
He got an 80 percent.
Step-by-step explanation:
We can solve this two different ways. I'll do both, and you choose which one makes the most sense:
We can divide the fraction 3/4 by 12. remember, when we divide fractions, we flip the second fraction and change the sign to multiplication:
3/4 ÷12 [starting equation]
3/4 x 1/12 [flip and change sign]
3/48 [now reduce]
1/16 Each step takes 1/16 of an hour.
1/16 x 60 = 3 3/4, or 3.75 minutes
Second way:
3/4 of an hour is 3/4 of 60...45 minutes.
Still, we divide out:
45 ÷ 12 [starting equation]
3 9/12 [divide with remainder]
3 3/4 minutes...3.75 minutes
