To make this easier, we can convert the fractions into decimals. 3/4 is 0.75. 1 and 1/2 would be 1.50 and 2 and 1/4 would be 2.25. Now, let us to the subtraction in order for us to know the difference of each. So 1.50 minus 0.75 would be 0.75. And 2.25 minus 1.50 is also 0.75. 0.75 is 3/4 and this means that she increased 3/4 hour each day.

yulyashka [42]

Answer:

10,740 money does she ean.

Step-by-step explanation:

Given: Mrs Miller sells a house for 179,000.

She earns a commission of 6%.

we set up a proportions to find how much she earn.

Let x be the money does she earns then;

\frac{179000}{100} =\frac{x}{6}

Simplify:

1790 = \frac{x}{6}

Multiply both sides by 6 we get;

1790 \times 6 = x

Simplify:

x = 10,740

Therefore, she earns money is, 10,740

What strategy can be used to solve 8 x 25 x 23
wariber [46]
The best way to multiply complicated problems mentally* is to break them into chunks.

Start with 20 times 8 to get 160, and then 8 times 5 to get 40. Add these together to get 200. 200 times 3 is 600, and 20 times 200 is 4000. Add these together to get your final answer, 4600. 

In other words 8 x 20 + 8 x 5 = 200  200 x 3 + 200 x 20 = 4600

*I assumed you meant mentally, because otherwise you'd just multiply longhand, multiplying two of the three numbers and then multiplying their product with the third.
