10 problems for every 7 minutes...

35 problems for every x minutes...

$\frac{10}{7}=\frac{35}{x}$

...multiply across

10x = 245

...divide

x = 24.5

it will take amber 24.5 minutes to complete 35 problems

25% or 1/4 because 5 is 25 percent of 20 and if you change 25% into a decimal you get .25 which is equivalent to 1/4
