1) She can make 13 skirts.
[tex]10 \frac{3}{4} \div 1 \frac{1}{4} = 10 \frac{3}{4} \times 1 \frac{4}{1} = 10 \frac{12}{4} \div \frac{4}{4} = 10 \frac{3}{1} or13[/tex]
2) There are 80 pieces of lace can be cut.
[tex]30 \div \frac{3}{8} = \frac{30}{1} \times \frac{8}{3} = \frac{240}{3} \div 3 = \frac{80}{1} or80[/tex]
