Question

To make marbled paper, Shannon filled a rectangular 279/10cm by 178/10cm dish with water. Then they gently swirled paint on top of the water. let a represent the area of the dish.

Select 1 multiplication and 1 division equation to represent the relationship.

choose 2 answers

A) 178/10 x a = 279/10

B) 178/10 x 279/10 = a

C) 279/10 ÷ 178/10 = a

D) a ÷ 178/10 = 279/10

Answer 1

The area of the dish, a, can be represented by the product of its length and width. Thus, we can write:

a = (279/10) cm x (178/10) cm

Simplifying this expression, we get:

a = 4953/100 cm^2

So, the correct equations are:

B) 178/10 x 279/10 = a

and

D) a ÷ 178/10 = 279/10
