Answer:

15

Step-by-step explanation:

you can't divide 4/15 down to have a denominator of 5 since 4 cant divide by 3 evenly

you can't divide 15 by something to get 10

so the only answer is 15

so 1/5 would turn into 3/15 by multiplying the top and bottom by 3

You have to work in factors of 5 because thats what they have in common

Answer:

15

Step-by-step explanation:

1/5+4/15=3/15+4/15

We have our common denominator.

We have to multiply the numerator with the denominator.

We multiplied 5 by 3 to get to 15, so we do the same to 1:

3/15+4/15=7/15

Rafael want to buy the same number of gifts bags and bows gifts bags are sold in packs of 6. Bows are sold in packs of 9. What i
GenaCL600 [577]

Answer:

Rafael should buy 9 gift bags and 6 bows packet so, that she can have SAME NUMBER OF ITEMS, i.e 54.

Step-by-step explanation:

The gift bags are sold in the packs of 6.

So, the number of gift bags in 1 packet  = 6 gift bags

The number of gift bags in 2  packet  = 6 x 2 gift bags  = 12  gift bags

The number of gift bags in 3  packet  = 6 x 3 gift bags  = 18  gift bags

And continuing similarly, we get

The number of gift bags in 9  packet  = 6 x 9 gift bags  = 54 gift bags.. (1)

The bows are sold in the pack of 9.

So, the number of bows in 1 packet  = 9 bows

The number of bows in 2 packet   = 9 x 2 bows  = 18 bows

The number of bows in 3 packet   = 9 x 3 bows  = 27 bows

And continuing similarly, we get

The number of bows in 6  packet  = 9 x 6 bows  = 54 bows... (2)

Here, comparing both equations (1) and (2) , we get

The number of gift bags = 54  = The number of bows.

Hence, Rafael should buy 9 gift bags and 6 packet of bows so, that she can have SAME NUMBER OF ITEMS, i.e 54.
