4. A wood was saw into 6 equal parts. Vicente and his friends painted all the parts. Which fraction shows the parts that were painted?

The correct answer is 6/6 or six-sixths because all of the 6 equal parts of the wood were painted by Vicente and his friends. This means that the entire wood was painted, which can be represented by the fraction 6/6 or the term six-sixths.

Explanation

The correct answer is 6/6 or six-sixths because all of the 6 equal parts of the wood were painted by Vicente and his friends. This means that the entire wood was painted, which can be represented by the fraction 6/6 or the term six-sixths.

8. Equivalent fractions are fractions that have the same value even they look different.

True

False

Equivalent fractions are fractions that represent the same amount or value, but are expressed in different forms. This means that even though they may have different numerators and denominators, they still represent the same quantity. For example, 1/2 and 2/4 are equivalent fractions because they both represent half of a whole. Therefore, the statement "Equivalent fractions are fractions that have the same value even they look different" is true.

9. When subtracting similar fractions, subtract the numerators and add the denominators.

True

False

When subtracting similar fractions, you actually subtract the numerators and keep the denominators the same. This is because when the fractions have the same denominator, you can directly subtract the numerators to find the difference. Adding the denominators is not necessary in this case. Therefore, the correct answer is false.

10. Change the underlined word to make the statement correct. 3/5 of the 20 santols are ripe. Four (4) santols are ripe.

Ten (10)

Eight (8)

Twelve (12)

The statement says that 3/5 of the 20 santols are ripe, which means that there are 12 ripe santols (3/5 x 20 = 12). However, the statement incorrectly states that there are four ripe santols. Therefore, the correct answer is twelve (12) to accurately reflect the given information.

Explanation

The statement says that 3/5 of the 20 santols are ripe, which means that there are 12 ripe santols (3/5 x 20 = 12). However, the statement incorrectly states that there are four ripe santols. Therefore, the correct answer is twelve (12) to accurately reflect the given information.

11. Which number will make the fractions 3/4 = ?/12 equal?

3

6

9

Equivalent fractions are fractions that are equal in value but different in form like 3/4 and 9/12. 3/4 x 3/3 = 9/12

Explanation

Equivalent fractions are fractions that are equal in value but different in form like 3/4 and 9/12. 3/4 x 3/3 = 9/12

14. Proper fractions are always less than 1.

True

False

Proper fractions are defined as fractions where the numerator (the top number) is smaller than the denominator (the bottom number). Since the numerator is always smaller, the fraction as a whole will always be less than 1. Therefore, the statement "Proper fractions are always less than 1" is true.
