Answer: 9 and 3/7
Step-by-step explanation: To multiply a mixed number by a mixed number, we first want to write each mixed number as an improper fraction.
We can write a mixed number as an improper fraction by multiplying the denominator by the whole number and adding the numerator.
We can change
to the improper fraction 30/7.
We can also change
to the improper fraction 11/5.
Now, we are simply multiplying fractions. To multiply fractions, we multiply across the numerators and multiply across the denominators. When we multiply these fractions, we will end up with the fraction 330/35. Since 330/35 is not in lowest terms, we need to divide both the numerator and denominator by the greatest common factor of 330 and 35 which is 5 and we will get the improper fraction 66/7.
Notice however that 66/7 can be changed into a mixed number by dividing the denominator which is 7 into the numerator which is 66.
66 divided by 7 equals 9 with a remainder of 3 so we can write 66/7 as the mixed number 9 and 3/7.
Therefore, 4 and 2/7 × 2 and 1/5 = 9 and 3/7
if you were to multiply 9 by 6 you would get 54, so yes its true.
6(x + 4) = 2(y + 5)..........Multiply everything out
6x + 24 = 2y + 10..........Solve for 2y by subtracting 10 from both sides
6x + 24 - 10 = 2y + 10 - 10
6x + 14 = 2y..................Solve for y by dividing both sides by 2
2y/2 = (6x + 14)/2
y = 3x + 7......................ANSWER.
