To sum two fractions, you have to transform them in order to have the same denominator: if you multiply both numerator and denominator of the first fraction by 8, and numerator and denominator of the second by 3, you have
Now we can easily sum the fractions, because we only have to sum the numerators:
Answer:
1/4 of the brownies were eaten
there were 1 - 1/4 = 3/4 of brownies left
2/3 of the 3/4 were eat or: (2/3)(3/4) = 1/2 of the whole pan of brownies were eaten
the total of brownies eaten is: 1/4 + 1/2 = (1*1 + 2*1)/4 = 3/4 of the whole pan of brownies were eaten.Step-by-step explanation:
It would be 7/13 since 7 balls out of the total 13 are not white.
Answer:
18x + 28 is the perimeter
Step-by-step explanation:
As perimeter is the som of all side
So P = 6x+8 + 3x+6 + 6x+5 + 2x+2 + 3 + x+4
= 6x+3x+6x+2x+x + 8+6+5+2+3+4
= 18x + 28
