I'm assuming your allowed to use a calculator for this? That's what I would do.

To go about the fraction, take the whole number and times it by the denominator, then add in the numerator to create a new fraction(a whole one not mixed). Then simply divide the numerator by the denominator.


193 is the new numerator and the new whole fraction is this and dividing it out gives you,

For the third one, just input it into a calculator,

Answer:
10 times greater
Step-by-step explanation:
When you write these as numbers, you get:
800,000,000 (8 hundred million place)
80,000,000 (8 ten million place)
Then divide the greater number by the less number:
800,000,000/800,000,00
make this easier by eliminating 0's:
80<u>0,000,000</u>/8<u>0,000,000</u>
80/8
10
10 times greater is your answer
Hope this helps!
