Answer:

1. \frac{3}{8}

2. \frac{3}{10}

Explanation:

The problems above tackle on the<em> "multiplication of fractions."</em>

Let's solve.

a. \frac{3}{4} x \frac{1}{2} = \frac{3}{8}

  • All you have to do is to <u><em>multiply the numerator of one fraction to the other</em></u>, and also<em><u> multiply the denominator of one fraction to the other.</u></em>
  • Numerator: 3x1 = 3
  • Denominator: 4x2 = 8

b. \frac{4}{7} x \frac{21}{40} ⇒ \frac{1}{1} x \frac{3}{10} = \frac{3}{10}

  • All you have to do is to get the <em>"Greatest Common Factor</em>" among the fractions. The GCF of 4 and 40 is <em>4</em>, so you have to divide both of them by 4. The GCF of 7 and 21 is 7, so you have to divide both of them by 7.

"do you need something from my daughter." What are the TWO errors in this sentence?
Grace [21]

Answer:

It should be

"Do you need something from my daughter?"

Meaning, the first letter of the sentence should be capitalized and since it's a question, it needs to end in a question mark.
