What is –3 2/3 · (–2 1/4 )?

algol [13]

$-3\frac{2}{3}\cdot\left(-2\frac{1}4{}\right)=\\--------------------\\negative\ number\ multiply\ by\ negative\ number\ is\ a\ positive\ number\\--------------------\\-3\frac{2}{3}\cdot\left(-2\frac{1}4{}\right)=3\frac{2}{3}\cdot2\frac{1}{4}=\\------------------------------\\$

if you want to multiply mixed numbers you need to turn them into improper fractions

$3\frac{2}{3}\cdot2\frac{1}{4}=\frac{3\cdot3+2}{3}\cdot\frac{2\cdot4+1}{4}=\frac{9+2}{3}\cdot\frac{8+1}{4}=\frac{11}{3}\cdot\frac{9}{4}=\frac{11}{1}\cdot\frac{3}{4}=\frac{11\cdot3}{1\cdot4}\\\center\boxed{=\frac{33}{4}=8\frac{1}{4}}$

Sue has saved $54 more than Bill

Step-by-step explanation:

Given

Sue saves $5 a week. so after 36 weeks he will have

= 36 * 5

= $180

Bill's saving is modeled by

m = 3.5w where w is the number of weeks

After 36 weeks,

$m = 3.5 * 36\\=126$

The difference between savings of Bill and Sue

$= 180-126\\=54$

Hence,

Sue has saved $54 more than Bill
