Answer:

2.4 hr. = time working together

Step-by-step explanation:

Let x = time working together

x/6 = work done by Martin

x/4 = work done by Victor

Martin's part + Victor's part = 1 jog done

x/6 + x/4 = 1 Multiply thru by 12

2x + 3x = 12

5x = 12

x = 2.4 hr.

Stephen uses

Answer:

13.75 servings or 13 ¾ servings

Step-by-step explanation:

This is the correct question

Stephen uses 2/25 kilograms of tofu in each serving of his famous tofu dish. He has 1 1/10 kilograms of tofu.

To get answer

We will have to divide the number of tofu required with the number of tofu own.

Stephen uses 2/25 kilograms of tofu in each serving and he has 11/10 kilograms tofu.

= (11/10) ÷ (2/25)

11/10 * 25/2 =

275 ÷ 20= 13.75 servings or 13 ¾ servings

Stephen can make 13 ¾ or 13.75 servings
