From the instructions i gather it might be like this
<span>(2*h)/15 = 20 // - 20
(2*h)/15-20 = 0
2/15*h-20 = 0 // + 20
2/15*h = 20 // : 2/15
h = 20/2/15
h = 150
h = 150</span>

Answer:
45 pages in 1 hour
Step-by-step explanation:
Find the unit rate by dividing the number of pages by the number of hours
135/3
= 45
This means he can read 45 pages in 1 hour.
The unit rate is 45 pages in 1 hour.
3/10 + 17/100
first make the 10 of the 3/10 turn into a 100 so it will make the 100 of the 17/100.
to make 10 turn into a 100 you multiply it by 10. if you're going to multiply the bottom number by 10 then you have to do the same thing with the top number:
3/10 * 10/10
3*10=30
10*10=100
new equation:
30/100 + 17/100
now just add the top numbers and leave the 100's alone:
<span>30/100 + 17/100
</span>30+17=47
<span>30/100 + 17/100 = 47/100</span>
