#12# sugar bowls

Explanation:

It's just 8 divided by 2/3

But, dividing by a fraction is the same as multiplying by its reciprocal...

So,

#=8/1*3/2#

#=12#

Explanation:

Often fraction questions are difficult to interpret because we generally only use the most common fractions in every day life.

The first decision is always "What operation is it?"

Make up a similar question with easy numbers:

Compare this question filling sugar bowls with:

"How many groups of 6 children can we form with 48 children?"
#rarr 48 div 6 = 8#

"How many bags of sweets with 5 in a bag can be made with 45 sweets?"#rarr 45 div 5 = 9# bags.

"How many servings of half a pizza can we get from 7 pizzas"
#rarr 7 div 1/2 = 7/1 xx2/1 =14 # servings

So the operation you need to do is division. # 8 div 2/3#

#8/1 div 2/3" "larr# change 'divide' to 'multiply by the reciprocal'.

=#cancel8^4/1 xx3/cancel2" "larr# cancel if possible

=#12 # bowls
