70%=70/100=7/10

what you do is shade 7 of the squares and say that is 21
now each square is worth the same
so 21/7=3
each square is worth 3

10 squares
3 times 10 is 30
the number is 30

I need help with this question

quester [9]

Answer:

2/5-1/4=8/20-5/20=3/20

Step-by-step explanation:

so you would have to multiply the fractions so that they have the same denominator, so multiply 2/5 by 4 to get 8/20 for the first blank. then do the same for the next blank but multiplying by 5 which would make it 5/20. then it equals 3/20 by using normal subtraction of the numerators (hope this is correct im sorry if its not).
