32 = 12 1/4 + 6 1/3 +x

get a common denominator for the fraction, 12

32 =  12 (1/4 * 3/3) + 6 1/3*4/4 + x

32 = 12 3/12 + 6 4/12 + x

add

32 = 18 7 /12 + x

subtract 18 7/ 12 from each side

32 - 18 7/12 = x

borrow from 32

31 12/12 - 18 7/12 = x

13 5/12 =x

Choice A

n200080 [17]

Answer:

The number of pies does the baker have left is 15.

Step-by-step explanation:

Given : A baker made 20 pies. A Boy Scout troop buys one–fourth of his pies, a preschool teacher buys one–third of his pies, and a caterer buys one–sixth of his pies.

To find : How many pies does the baker have left?

Solution :

Let x be the number of pies does the baker have left.

According to question,

Number of pies buys,

One-fourth =\frac{1}{4}

One-third =\frac{1}{3}

One-sixth =\frac{1}{6}

i.e. x=20-(20\times \frac{1}{4}+20\times \frac{1}{3}+20\times \frac{1}{6})

x=20-(5+20\times \frac{1}{3}+10\times \frac{1}{3})

x=20-(5+\frac{20+10}{3})

x=20-(5+ \frac{30}{3})

x=20-(5+10)

x=20-(15)

x=5

The number of pies does the baker have left is 15.
