Henry did 5 6 of his math problems. the next day, he checked 2 3 of the homework problems he did the night before. what fraction of the homework problems did he check?

Step-by-step explanation:

We are told that Henry did 5/6 of his mathematics problems. And then he checks 2/3 of the problems. So we are meant to find what 2/3 of 5/6 is.

The word "of" in mathematics is normally a good indicator of multiplication, especially where fractions, decimals and percentages are involved. So finding one fifth of 260 is done by multiplying one fifth by 260.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
