So we have to put the value of 1:3 in a ratio

1 : 3
= 3:y

Ask yourself what do I have to multiply one by to get three ( the answer is three)
Because one side is multiplied by three, you have to multiply the right hand side by three to get y
3*3 is 9

Therefore, the y for 3 hours is 9

Then, we have to make another ratio
1:3
= 5:x

Ask yourself what do I have to multiply by one to get five (the answer is five)
So you multiply the other side by five as well
3*5=15

Therefore, the y for five hours is 15

3/4-1/8=? thank you❣️
Helen [10]
Convert them into similar fractions, so you take 3/4 and multiply the top and bottom by 2. Now you have 6/8

So, you do not subtract the denominators (bottom number) only the numerators (top number).

6-1 = 5

Afterwards, you put it back over 8, giving you 5/8

3(x−7)=6(x−10)<br> Solve For X<br>3x-21=6x-60
stepladder [879]
3(x-7)=6(x-10)
3x-21=6x-60
3x-21+21=6x-60+21
3x=6x-39
3x-6x=6x-39-6x
-3x=-39
-3x/-3=-39/-3
x=13
