Mathew has
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,

<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


<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

Make the denominators same for easier calculations

Converting again to mixed fractions we get,

Thus Mathew has
more brown rice than white rice
