I actually just learned this in 8th grade and it was so easy its crazy but its honestly simple it helps you solve the triangles and things and the equation is a squared + b squared = c squared and the a and b you would plug in the sides of the triangle or whatever shape your working with and square those numbers then find c by adding the two and then you square the c at the end and that will be your answer.
The first one seems more reasonable
Answer:
9/20
Step-by-step explanation:
First you'd do 3/5 x 3/4 because the denominators aren't the same. When you multiply them you get 9/20. That's your answer! If your not satisfied look it up on Google lol.
Fill in the values and calculate:
1/4 * 6 + 3*7 = 6/4 + 21 = 22 1/2
6 / 8 = 3/4
3/4 x 7 = 5 1/4
5 1/4 = $5.25
So, 7/8 of a pound of shrimp costs $5.25.
