Answer:
2.59 x 10-3 = 22.9
and 22.9 in standard form is Your number written in expanded form is:
20 + 2 + 0.9
First of all, observe that all fractions exist as long as b is not zero.
Multiply both numerator and denominator of the first fraction by 3:

Now all fractions have the same denominator. Under the assumption that b is not zero, multiply both sides by 3b:

Subtract 3b from both sides:

Subtract 2 from both sides:

Divide both sides by 2:

8.25/3 = $2.75 per ice cream
2.75 * 2 = $5.50
It would cost $5.50 for 2 ice cream
you will need 3/8 pounds of peanut.
3/8 + 1/4 + 1/8= 3/4
(ask me if you are confuse plz)
Divide by 12 BC it really be like that sometimes
