Katyanochek1 [597]

There are \frac{5}{12} of these components together

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

As a science experiment Mo and Jo want to send their rocket into space

They need 1/4 cup of water and 1/6 cup of a secret component

From given question,

\text{Cup of water} = \frac{1}{4}\\\\\text{Cup of secret component } = \frac{1}{6}<em><u></u></em>

<em><u>How much is there of these two components together?</u></em>

So we need to add these together

\text{Cup of water}+ \text{Cup of secret component } = \frac{1}{4} + \frac{1}{6}\\\\\text{Cup of water}+ \text{Cup of secret component } = \frac{1 \times 6}{4 \times 6} + \frac{1 \times 4}{6 \times 4}\\\\\text{Cup of water}+ \text{Cup of secret component } =\frac{6}{24} + \frac{4}{24}\\\\\text{Cup of water}+ \text{Cup of secret component } = \frac{6+4}{24} = \frac{10}{24} = \frac{5}{12}

Thus there are \frac{5}{12} of these components together
