What are the steps to divide 417.2 divided by 17.2 (I know what the answer is but how do you get to it)

Valentin [98]

You could start by noticing

$\dfrac{417.2}{17.2}=\dfrac{\frac{4172}{10}}{\frac{172}{10}}=\dfrac{4172}{172}$

so you don't have to worry about the decimal point anymore. Then carry out the division as usual.

172*24 = 4128

so we have

4172 = 4128 + 44 = 172*24 + 44

$\implies\dfrac{417.2}{17.2}=\dfrac{4172}{172}=24+\dfrac{44}{172}$

Nuts.com sells raw almonds for $10 per pound and roasted pistachios for $12 per pound. Christopher spends $70, before taxes and

sp2606 [1]

Christopher purchased 2.8 pounds of almonds and 3.5 pounds to roasted pistachios.

Step-by-step explanation:

Cost of almonds per pound = $10

Cost of roasted pistachios = $12

Total amount spent = $70

Weight of nuts = 6.3

Let,

Weight of almonds = x

Weight of roasted pistachios = y

According to given statement;

x+y=6.3 Eqn 1

10x+12y=70 Eqn 2

Multiplying Eqn 1 by 10

$10(x+y=6.3)\\10+10y=63\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2;

$(10x+12y)-(10x+10y)=70-63\\10x+12y-10x-10y=7\\2y=7$

Dividing both sides by 2

$\frac{2y}{2}=\frac{7}{2}\\y=3.5$

Putting y=3.5 in Eqn 1

$x+3.5=6.3\\x=6.3-3.5\\x=2.8$

Christopher purchased 2.8 pounds of almonds and 3.5 pounds to roasted pistachios.
