We have to rewrite the expression so that it has no denominator.
For example:
1 / x = x^(-1)
1/8 = 8^(-1); 1/x^(4) = x^(-4); 1/y^(3) = y^(-3); 1/z = z^(-1).
To multiply a fraction, imagine it this way. Start with 1/4. Then if you multiply 1/4 by 2 it would be 1/2.
If you have a quarter, and you times that quarter by 2, you have half a dollar.
It only needs to be simplified if you can simplify the fraction.
Answer:
306+7÷100=306.07 that is the answer
Answer:
18
Step-by-step explanation:
a + 7b + 4c = 2,
Multiply this equation by 9
9( a + 7b + 4c) = 2*9
9a + 63b +36c = 18
Rearrange the order
36c +9a +63b = 18
60 min/ (20/100)
= 60 min* (100/20)
= 300 min.
60 minutes is 20% of 300 blank minutes~
