The ratio Tim spends on math homework to science homework is 5 to 4. If he spends 40 minutes on math homework, how many minutes does he spend on science homework?
A. 20 Minutes
B. 32 Minutes
C. 60 Minutes
D. 90 Minutes
I think it's either A or B, but I don't know.
5/4 = 40/x
Cross multiply and solve for x.

Well, it seems like Tim is quite the math enthusiast. With a ratio of 5 to 4, we can deduce that for every 5 units of time he spends on math, he spends 4 units of time on science.
So, if Tim spends 40 minutes on math homework, we can set up a proportion: 5/40 = 4/x, where x represents the number of minutes he spends on science.
To solve for x, we cross-multiply: 5x = 4 * 40, which simplifies to 5x = 160.
Dividing both sides by 5, we find that x = 32.
Therefore, Tim spends 32 minutes on science homework.
So, the answer is B. 32 minutes. Tim has got his science game on point too! Keep up the good work, Tim!
To find out how many minutes Tim spends on science homework, we can set up a proportion based on the given ratio:
Math homework:Science homework = 5:4
Since we know Tim spends 40 minutes on math homework, we can set up the proportion as:
40 minutes:x minutes = 5:4
To solve the proportion, we can cross multiply:
40 * 4 = 5 * x
160 = 5x
To isolate x, divide both sides of the equation by 5:
160/5 = x
x = 32
Therefore, Tim spends 32 minutes on science homework.
The correct answer is B. 32 Minutes.
To find the number of minutes Tim spends on science homework, we can use the ratio given: 5 to 4.
Let's set up a proportion to solve for the unknown number of minutes Tim spends on science homework:
(5 minutes of math homework) / (4 minutes of science homework) = (40 minutes of math homework) / (x minutes of science homework)
Cross-multiplying, we get:
5x = 40 * 4
Dividing both sides of the equation by 5:
x = (40 * 4) / 5
x = 160 / 5
x = 32
Therefore, Tim spends 32 minutes on science homework.
The correct answer is B.
