Question

Three friends tayo, titi and tunde shared a quantity of walnuts on the ratio 3:4:5. if tayo got 21 walnuts, how many did titi get?​

Answer 1

titi got 28 walnuts

Explanation:

If we have the ratio of walnuts for each person and at least one value, we can solve for the other values.

tayo : titi : tunde

3x : 4x : 5x (x is just a variable for the exact quantity of walnuts relative to the ratio)

If tayo has 21 walnuts, this means that

3x = 21

We can solve this equation for x

3x=21

21/3=7

x=7

Now that we know x, we can plug it in for the other values to solve for the amount of walnuts that titi and tunde have.

If titi has 4x walnuts, and x=7, then we can solve for the amount of walnuts titi has.

4*7=28

Therefore, titi has 28 walnuts
