In a basket, 3/4 of the fruits are oranges and the rest are apples. After I have away 10 oranges, there are now 1/2 as many oranges as apples. How many apples and oranges are there in the basket?

Answer 1

.75 fruits = orange or .75 f = oj
.25 fruits = apples or .25 f = a

oj - 10 = .5 a
so
.75 f - 10 = .125 f

.625 f = 10

f = 16 answer

now
check
12 + 4 = 16 yes
12 - 10 = 2
2 = half of 4 yes
