SashulF [63]

Answer:

\displaystyle3\frac{3}{4}

Step-by-step explanation:

Hi there!

4\displaystyle\frac{11}{16} \div1\frac{1}{4}

Change mixed numbers to improper fractions:

= \displaystyle\frac{75}{16} \div\frac{5}{4}

Dividing by a fraction is the same as multiplying by its reciprocal:

= \displaystyle\frac{75}{16} *\frac{4}{5}

Reduce:

= \displaystyle\frac{75}{4} *\frac{1}{5}

= \displaystyle\frac{15}{4} *\frac{1}{1}

= \displaystyle\frac{15}{4}

Change improper fraction into mixed number:

= \displaystyle3\frac{3}{4}

I hope this helps!

kolbaska11 [484]

Answer:

Five= 9 One= 6 Twenty= 15

Step-by-step explanation:

A cashier has a total of 30 bills, made up of ones, fives, and twenties.

o+f+t=30,

The number of twenties is 9 more than the number of ones.

t=9+o,

The total value of the money is $351.

o+5f+20t=351

so we have

o+f+t=30, t=9+o,

o+5f+20t=351

f = 9, o = 6, t = 15
