Grace has 3 1/2 cups of yogurt to make smoothies. Each smoothies uses 2/5 cup of yogurt. What is the maximum number of smoothies that Grace can make with the yogurt?

Let’s convert the yogurt first,
3 1/2 cups of yogurt covert it 3x2=6 therefore is 7/2, then covert into factor of 5. 7/2 x 5/5 = 35/10 yogurt
Each smoothies cost 2/5 cup of yogurt, covert it to factor of 10. 2/5 x 2/2 = 4/10. There for use 35/4 = 8 and remainder is 3.
So the solution is 8 yogurt

Slope formy2-y1/x2-x1(-2,-3) and (3,7))/ ) = 10/5the slope is 2the answer is bhope this !
