Shelby's Ice Cream Shop sold 8 sundaes with nuts and 4 sundaes without nuts. What is the ratio of the number of sundaes with nut

Romashka-Z-Leto [24]

Answer: 2:1

Step-by-step explanation:

The ratio of A to B is given by : $\dfrac{A}{B}$ or A : B .

Given : sundaes with nuts = 4

sundaes without nuts = 8

The ratio of the number of sundaes with nuts to the number of sundaes without nuts = $\dfrac{8}{4}=\dfrac{2}{1}\ \ \ [\text{Divide numerator and denominator by 4 }]$

= 2:1

hence, the required ratio = 2:1 .
