Answer:
The novel has 2160 pages.
Step-by-step explanation:
The number of pages of the novel is x.
Mica has read 1/2 of the novel, so x/2 = 0.5x.
Denise has read 2/5 of the novel, so 2x/5 = 0.4x.
Mica has read 216 pages more than Denise
This means that:
0.5x - 0.4x = 216
0.1x = 216
x = 216/0.1
x = 2160
The novel has 2160 pages.
Answer:
We need 1 cup of sugar for 2 cups of bananas
Step-by-step explanation:
We can use proportions to solve this problem. Put bananas on the top and sugar on the bottom
3 cups 2 cups bananas
-------------- = ------------------
1 1/2 cups x cups sugar
Using cross products
3 *x = 2 * 1 1/2
Changing to decimals
3x = 2* 1.5
3x = 3
Divide by 3
3x/3 = 3/3
x=1
We need 1 cup of sugar for 2 cups of bananas
