Question

Kim knows she should keep her fat intake to less than 130 grams per day if on a 4,000 calorie diet. She is on a 1,500 calorie per day diet. How many grams of fat should she limit herself to each day?

Answer 1

do you know about ratios and proportions ?

Answer 2

write a ratio of fat grams/ calories

Answer 3

yes but it has been I really long time since I have done stuff like this

Answer 4

Use this info to write the first ratio:
130 grams per day if on a 4,000 calorie diet.

Answer 5

130/4000

Answer 6

and for the second ratio, call the "unknown fat grams" x with 1500 calories

Answer 7

x/1500

Answer 8

and set the ratios equal
\[ \frac{x}{1500} = \frac{130}{4000} \]
to "solve for x" multiply both sides by 1500, like this:
\[ \frac{x}{1500} \cdot 1500= \frac{130}{4000} \cdot 1500\]
and simplify both sides

Answer 9

I got 195000

Answer 10

on the left side x *1500/1500 is x*1 = x
on the right side, 130*1500/4000
try again

Answer 11

apparently you did 130*1500 but did not divide by 4000

Answer 12

oh that would be 48.75

Answer 13

yes. so the answer is 48.75 grams, or if you round to the nearest gram, about 49 grams
