Explanation:

Question 1

In the number 7,890,342, we determine the place value of the digit 3. The digits are grouped by place values: millions, hundred thousands, ten thousands, thousands, hundreds, tens, ones. The 3 is in the hundreds place, so its place value is three hundred. The term for this is "place value".

Fractions like $\frac{1}{4}$ and $\frac{2}{8}$ have the same value (since $\frac{2}{8}=\frac{1}{4}$) but different numerators and denominators. These are called equivalent fractions because they are equal in value.

The expression $\frac{1}{2} \times$ base $\times$ height is a formula used to calculate the area of a triangle. A formula is a mathematical relationship or rule expressed in symbols.

Answer:

Place value
