3*5+5 = 20
2+3=5... 5x4=20... 20+1=21 !
two 20 dollar bills and one 5 dollar bill; two dimes and one penny
4 x 5 + 6 - 3!
factor: 15=3*5 20=2*2*5 35=5*7 so 5 is common to all only need it once LCM=5*3*2*2*7= 420
2 x 2 x 5 = 20 3 x 3 x 5 = 45 The GCF is 5.
(5+7)*(5-3)=12*2=24
101
4+3=5+2 or 4+5=32
4*5 + 6/3 = 20 + 2 = 22
There are not 20 ways - there are only 12.
- 1 + 2 + 3 + 4*5 + 76 = -1 + 5 + 20 + 76 = 4 + 20 + 76 = 100
I think the answer is 20/3 because 4*5=20 that's the biggest number those three numbers can make. the numerator is 3 and the denominator is 20.
