This can be done algebraically:
300*x=330 Where x is the multiplier
Therefore x=330/300=1.1
To find a percentage of a number you multiply by the percentage divided by 100.
So 330 is 110% of 300, which is an increase of 10%.
1 and 1/2 is the scale factor
Answer:
6 runners finished the race
Step-by-step explanation:
it starts with 90 runners. then 1/3 of them dropped out in the second half of the race, that means you do 90 divided by 3
90 ÷ 3 = 30
Then, 1/5 of the runners remained.
That means you do 30 divided by 5
30÷ 5= 6
so the answer is 6 remaining runners finished the race.
7 copies I assume means multiplication. 7 x 1/4=7/4. When multiplying fractions, the numerator is multiplied.
Your answer is 35 because you do 35 divided by 50 which equals 0.7 starting from the decimal, move two spaces to the right and you will get 70%
