How do you work out what 35% of 250 is

Answers

'of' is multiplication.

35% is a percentage, and percentages are parts of 100, so divide 35 by 100.

$\sf35/100=0.35$

So we have:

$\sf0.35*250$

Multiply:

$\sf87.5$

what I do is what is 1% of 250?, 2.5, right? so what is 2.5x35? 87.5 would be your answer. or you could do .35(percentage before multiplying by 100)x250, either way works.

Ms. Turner drove 825 miles in March. She drove 3 times as many miles in March as she did in January. She drove 4 times as many miles in February as she did in January. What was the total number of miles Ms. Turner drove in February?

this is because u first have to find the miles she drove in january. since she drove 3 times as much in march than in january, u divide or 825 divided by 3 to get 275. since she drove 4 times as much in february of january, u multiply 275 by 4 to get 1100.

The sides of the large cake are 2 times the length of the sides of the small one.

-- The amount of the frosting depends on the area of the cake.
-- The area grows as fast as the square of the sides grows.
-- The ratio of the areas is the square of the ratio of the sides.

-- If you make the sides 2 times as long, the area becomes (2²) = 4 times as much.

-- If you made the sides 7 times as long, you'd need (7²) = 49 times as much frosting.

-- If you made the sides 10 times as long, you'd need 10² = 100 times as much.
