Hi! You need 3 boxes because if you divide 21 1/4 / 10 you get 2 1/8 or 2.125 so you at least have two boxes. You will still have some left over after the two boxes so you will need another box for those. I hope this helped, Goodluck :)
<em>x</em>² - x
<em>x</em> = 4
4² - 4
16 - 4 = 12
Hope this helps!
Answer:
there are 6/8 in 3/4
Step-by-step explanation:
if you want to change the denominator of the fraction, you must find the multiple of it,
(3/4) x 2 is 6/8
so you have 6 x (1/8) thats the same 6/8
3/4 is the minimum simplification, if you want to find the same fraction but with other denominator, you have to multiply 3/4 for any number, to do this you have to multiply the numerator and the denominator
Its simple take out the y and take out the x, you get 25=6!!!!!!!
I got 22 because if u do 20 multiplied by 10% that gives u 2 which u then add onto the 20 to get the starting price. 10% of 22 is 2 and then 22-2 = 20 (if u we’re doing it from the starting price)
