Question

PLEASE someone help me with this question, I’ve been stuck on it for so long :(

Help is greatly appreciated! I know what the answer is ( back of my textbook) but i dont know how to figure it out

Oh also if it’s possible could you please take a picture of your handwritten answer instead of typing it since its easier for me to understand , but either way is fine :)

Answer 1

13.5 litres

Explanation:

the ratios are 2 : 3 : 4 = 2x : 3x : 4x ( x is a multiplier )

given Henrietta produced 1.5 litres more than Gladys , then

4x = 3x + 1.5 ( subtract 3x from both sides )

x = 1.5

then total milk produced by the 3 cows is

total = 2x + 3x + 4x = 9x = 9 × 1.5 = 13.5 litres
