Answer:

88 noodles.

Step-by-step explanation:

We have been Mrs. Lau rolls 2 3/4 feet of dough to make noodles. If the noodles are 3/8 of an inch wide.

Convert 2 3/4 feet to inches by multiplying it by 12 as 1 feet equals 12 inches.

[tex]2\frac{3}{4}\text{ feet}=(2*12+12*\frac{3}{4})\text{ inches}=(24+9)\text{ inches}=33\text{ inches}[/tex]

To find the number of noodles, we will divide total amount of dough by width of each noodle.

[tex]\text{Number of noodles}=33\div \frac{3}{8}[/tex]

Convert division problem to multiplication problem by flipping the second fraction:

[tex]\text{Number of noodles}=33\times \frac{8}{3}[/tex]

[tex]\text{Number of noodles}=11\times8[/tex]

[tex]\text{Number of noodles}=88[/tex]  

Therefore, Mrs. Lau will make 88 noodles.
