Answer:
280ml of oil.
Explanation:
The first step to finding how much oil he should use, turn 5 : 2 into a fraction.
5 Since we know he uses 700ml of mayo, we use that to find the
2 amount of oil.
We use cross multiplication and use x for the amount of oil.
x = oil
5 = 700
2 x
2 x 700 = 1,400
1,400 ÷ 5 = 280
x = 280
In order to confirm if this is true, we check if the ratios are equivalent.
5/2 = 700/280
simplify 700/280 by finding the gcf
GCF = 140
700 ÷ 140 = 5
280 ÷ 140 = 2
5 : 2 or 5/2
Therefore, it is correct
