Mrs. Lau rolls out #2 3/4# feet of dough to make noodles, If the noodles are each #2/5# of an inch wide, how many noodles will she make?

Answer 1

#82# noodles with some dough left over to roll out and cut again.

The process will be to divide #2 3/4# feet by #2/5# of an inch.
#rarr# change feet into inches. #2 3/4# feet = #24+9 = 33# inches
(#2 3/4 xx 12 = 11/4 xx 12 = 11xx3 =33# inches)
#rarr# how many strips of #2/5# inch can be cut from #33# inches?
#rarr33 div2/5 = 33xx5/2 = 82.5# strips
She can make #82# strips and have some dough left over to roll out again.

Answer 2

To find the number of noodles Mrs. Lau will make, we need to divide the total length of dough by the width of each noodle.

Total length of dough in inches = 2 3/4 feet * 12 inches/foot = 33 inches

Number of noodles = Total length of dough / Width of each noodle Number of noodles = 33 inches / (2/5 inches) Number of noodles = 33 inches * (5/2) Number of noodles = 82.5

Therefore, Mrs. Lau will make 82.5 noodles.
