Multiplying mixed numbers and whole numbers 1 1/2 x 2/1 =
1 answer:
Answer: 3
Step-by-step explanation:
1. Convert the mixed number to fraction:
- Multiply the denominator of the fraction by the whole number.
- Add the product obtained and the numerator of the fraction.
- Write the sum obtained as the numerator and rewrite the original denominator of the fraction.
Then:
2. Multiply the numerators.
3. Multiply the denominator.
4. Reduce the fraction.
Then:

Assuming you made an error typing the question out, and the formula should say 30g, as it's $30 a round:
The reactangle has an area of x.
So that means two numbers multiplied to each other equal to x. We can just think of itwo numbers that when multiplied equal to x as a and b.
So that means the side lengths are <u />a and b. And ab = x (will be using this right next).
And it was multiplied by some scale factor that made the new area 9x. So if the scale factor is y, then:
y can not equal to -3, because the length of a side of any polygon can never be negative.
So the dilation is 3.
And so if the dimension is 5 by 8.
Then the area is
And so then
And then after the dilation, it would be
We could check it another way too. Since we said the scale factor is 3, then:
So basically 15 by 24 is the new dimensions :)
