Answer:
5
Step-by-step explanation:
40% means 40 parts out of 100. If we have made the numerator of the fraction 2, we have divided 40 by 20. To make this fraction equal to 40/100, we have to divide 100 by 20 as well, giving us 5.
The ratio is 1:4
She could use 4 gems and 16 flowers 4 x 4 = 16 7 stickers and 28 glue dots 7 x 4 = 28
80* 4/5
Cross out 80 and 5
You can divide by 5 for both of the numbers
80/5=16
5/5=1
16*4= 64
Answer is 64
Answer:
Same, because they are parallel.
Step-by-step explanation:
LCM(a, b) ≡ a×b/GCD(a, b)
LCM(6, 9) = 6*9/3 = 18 . . . . . . . (2 [ 3 ) 3] = 18 . . . ( ) product = 6; [ ] product = 9
LCM(2,5) = 2*5/1 = 10 . . . . . . . . (2 [ 1 ) 5 ] = 10
LCM(27, 45) = 27*45/9 = 135 . . (3 [ 9 ) 5] = 135
_____
In the above LCM products, the number in [ ) brackets is the GCD.
