Answer:
b. $5.80
c. 131.544
Step-by-step explanation:
To find b, first divide 1 7/20 into 78 3/10
[tex]78 \frac{3}{10} \div 1 \frac{7}{20} [/tex]
[tex] \frac{783}{10} \times \frac{27}{20} [/tex]
[tex] \frac{783}{10} \times \frac{20}{27} = \frac{15660}{270} [/tex]
[tex] = 58[/tex]
A dime is worth 10 cents so .58x10=$5.80.
c. Multiply the mass by 58.
[tex]2.268 \times 58 = 131.544[/tex]
