Answer:
1. Not accounting for the difference in the base of the exponent when applying the quotient rule.
2. Not subtracting the exponents of the denominator from the exponent of the numerator when applying the quotient rule.
90% of "a" is 44.......turn ur percent into a decimal...." of " means multiply..." is " means equals...
0.90a = 44...divide both sides by 0.90
a = 44 / 0.90
a = 48.89.....this is rounded
what is 30% of 3a.....and we know that "a" is 48.89...
0.30(3 * 48.89) = 0.30(146.67) = 44 <=== ur answer
3.7/2 = 1.85
2 goes into 3 1 time.
you have a remainder of 1
That one gets a 7 after it
now you have 17
2 goes into 17 8 times
remainder of 1
bring down the 0 that's there, but is not shown because it's not important in standard form or decimals.
You get 10 and that's 5
so you have 1.85
1.85$
