Answer:

The sum of an even number plus an odd number is odd.

Step-by-step explanation:

The sum of an even number and an odd number is odd.

For example:

2+3=5

11+10=21

51+32=83

The end digit of an even number is always 0, 2, 4, 6, or 8

The end digit of an odd number is 1, 3, 5, 7, or 9.

So if we add only the end digit of an even and an odd number we can find no combination that can give end digit 0, 2, 4, 6, or 8(i.e even).

Hence, the sum of an even number plus an odd number is odd.

Matthew has two kind of rice brown rice 8 7/8 and white rice 6 3/4 How much more brown rice than white rice does Matthew have?
pychu [463]

Mathew has \frac{17}{8} \text{ or } 2\frac{1}{8} more brown rice than white rice

<em><u>Solution:</u></em>

Given that Matthew has two kind of rice ; brown rice and white rice

From given question,

\text{Brown rice } = 8\frac{7}{8}\\\\\text{White rice } = 6\frac{3}{4}

<em><u>Let us convert the mixed fractions to improper fractions</u></em>

Multiply the whole number part by the fraction's denominator

Add that to the numerator

Then write the result on top of the denominator

\text{Brown rice } = 8\frac{7}{8} = \frac{8 \times 8 + 7}{8} = \frac{71}{8}

\text{White rice } = 6\frac{3}{4} = \frac{4 \times 6 + 3}{4} = \frac{27}{4}

<em><u>How much more brown rice than white rice does Matthew have?</u></em>

So we need to find the difference between brown rice and white rice

Difference = brown rice - white rice

difference = \frac{71}{8} - \frac{27}{4}

Make the denominators same for easier calculations

difference = \frac{71}{8} - \frac{27 \times 2}{4 \times 2}\\\\difference = \frac{71}{8} - \frac{54}{8}\\\\difference = \frac{71 - 54}{8} = \frac{17}{8}

Converting again to mixed fractions we get,

difference = \frac{17}{8} = 2\frac{1}{8}

Thus Mathew has \frac{17}{8} \text{ or } 2\frac{1}{8} more brown rice than white rice
