Answer:
a
Step-by-satep explanation:
There's two ways to do this.
The first way:
Work out the amount of sugar needed to make one cake, and then multiply that by 7.
30 grams ÷ 4 cakes = 7.5 grams for 1 cake.
7.5 grams × 7 cakes = 52.5 grams for 7 cakes.
The second way:
Work out the ratio of sugar:cake by doing 7 ÷ 4, and then multiplying that value by 30.
7 cakes ÷ 4 cakes = 1.75
1.75 × 30 grams = 52.5 grams for 7 cakes.
Either way, the answer is 52.5 grams.
Answer:
8.5
Step-by-step explanation:
Given the expression 12.75/1.5. The technique in solving the division expression is as shown
First we can write the decimals as fraction as shown;
12.75 = 1275/100
1.5 = 15/10
12.75/1.5 = (1275/100)÷(15/10)
12.75/1.5 = 1275/100×10/15
12.75/1.5 = 1275/10 × 1/15
12.75/1.5 = 1275/150
12.75/1.5 = 8.5
Hence the result of the division is 8.5
