Answer :
Answer:
a) Eva will need 2 bags of clay to make both pieces of pottery.
b) She will have leftover [tex]\frac{11}{10}[/tex] pounds of clay.
Step-by-step explanation:
Hi
a) We have to find the total amount of clay, as she needs [tex]\frac{3}{5}pound=P_{1}[/tex] and [tex]\frac{7}{10}pound=P_{2}[/tex], so [tex]P_{1}+P_{2}= \frac{3}{5} +\frac{7}{10} =\frac{6+7}{10}=\frac{13}{10}pounds[/tex], is the total amount of clay. Then as we Know that one bag of clay has [tex]\frac{4}{5} =\frac{8}{10} pounds[/tex], It isn´t enough, but with two bags [tex]2*\frac{8}{10}=\frac{16}{10} pounds[/tex], It is enough clay.
b) She will have leftover [tex]\frac{16}{10} -\frac{13}{10} =\frac{3}{10}pounds[/tex] of the second bag, then we add the third one, so [tex]\frac{3}{10} +\frac{8}{10} =\frac{11}{10}pounds[/tex] are leftover.
