Answer 1

390 cal

Explanation:

We have the ratio of 50 : 260, which can be simplified to 25 : 130, which as 25 is a factor of 75 we can use to figure ot the answer.

Now we just need to multiply both sides pf the ratio by 3 to get back too 75 : x

130 * 3 = 390, so the ratio is 25 : 390

Answer 2

390 calories

Explanation:

Divide 260 and 50, to find how much calories are in 1 gram.

260/50=5.2

1 gram=5.2 calories.

Now multiply 75 with 5.2 to find how many calories are in 75 g.

75 x 5.2=390

Final answer

390 calories
