2 1/4 ⋅ 1 2/3<br> as a mixed number

Gemiola [76]

Answer:

$3\frac{3}{4}$

Step-by-step explanation:

We have two mixed numbers and are asked to multiply them together.

2 1/4 * 1 2/3

First we convert the mixed numbers into improper fractions to make it easier for us. So follow the MA rule.

Multiply the whole number by the denominator and add the numerator.

2 1/4 * 1 2/3

9/4 * 5/3

Now multiply across,

$\frac{9*5}{4*3}$

$\frac{45}{12}$

Now we need to convert this back into a mixed number.

So how many times does 45 go into 12?

3 times, and 3 are left.

$3\frac{3}{4}$

Find the diameter of a circle that has an area of 254.34mm2

zvonat [6]

To find the diameter, divide the area(254.34) by pi(3.1415) and then square the quotient

$\frac{254.34}{3.1415} = 80.95$
$\sqrt{80.95} = 8.99$
That is the radius now just times that by 2 so 2 x 8.99 = 17.98

Now I have a felling the might be wanting 18 because 8.99 is so close to 9 and this is also true for 80.95. They probably want 80.95 = 81, which the square root of that is 9, which is the radius and if you times that by 2 the diameter would equal 18
