Question

How do I not know 4th grade math I really am 0iq

Answer 1

C
Just multiply 20 times the amount of a certain fabric used to make 1 toy
For example
Cristian uses 3/8 sheet of red to make one toy so multiply 3/8 by 20 and you get 7.5 but since you are calculating the number of full sheets they need you will round up to 8 sheets of red fabric

Answer 2

C) 8 sheets of red and 13 sheets of yellow felt

Explanation:

Red felt

Red felt needed for 1 toy = 3/8 sheet

⇒ Red felt needed for 20 toys = 20 × 3/8 sheets

`\sf \implies 20 * \frac38=(20)/(1)* \frac38=(20 * 3)/(1 * 8)=(60)/(8)=7\frac12`

Therefore, 8 complete sheets of red felt are needed.

Yellow felt

Yellow felt needed for 1 toy = 5/8 sheet

⇒ Yellow felt needed for 20 toys = 20 × 5/8 sheets

`\sf \implies 20 * \frac58=(20)/(1)* \frac58=(20 * 5)/(1 * 8)=(100)/(8)=12\frac12`

Therefore, 13 complete sheets of yellow felt are needed.
