77 over 21 = 11/377 ÷ 7 = 1121 ÷ 7 = 3
Yes, because 3 is the only number that both can be divided by to further reduce both sides. 21/3 = 7, 30/3= 10 so, 21/30 = 7/10
52/7 = 156/21 - 50/21 =106/21 or 5 and 1/21
7/21:= 7 ÷ 21= 0.333 in decimal
1 over 3 7/21 = 1/3
77 over 21 = 11/377 ÷ 7 = 1121 ÷ 7 = 3
6/7
21/27 = 7/9 by dividing the numerator and denominator by 3
yes because 3 goes into 9 and 21. so 9/21 simplified is 3/7.
Yes, because 3 is the only number that both can be divided by to further reduce both sides. 21/3 = 7, 30/3= 10 so, 21/30 = 7/10
Neither, Both fractions reduce to 3/7, so they are equal.
No
21/57 This will cancel down by '3' Hence 21/57 = 7/19 (/19 will not reduce any further, because both '7' and '19' are prime numbers.
7/21 in lowest term =1/3To reduce to lowest term:1. Get the GCF of 7 & 217 = 721=7 * 3======GCF=72. Divide the 7 & 21 by their GCF.7÷ 7 = 121÷ 7 = 3thus; lowest term is1/3.
7/8x = -21 multiply through by 8x 7 = -168x divide both sides by -168 and reduce fraction -1/24 = x check 7/8(-1/24) = -21 7// -1/3 = -21 -21 = -21 checks
52/7 = 156/21 - 50/21 =106/21 or 5 and 1/21
There is no way to reduce 7 over 8 because it is already in simplest form.
