Test: Sharing and Measuring - Class 4 MCQ

To determine what fraction of the garden is planted with roses:

• The garden is divided into five equal parts.
• Two parts are planted with roses.
• This means 2 out of 5 parts have roses.

Therefore, the fraction of the garden with roses is 2/5.

When you combine two pieces of 1/4, you simply add them together:

• Add 1/4 + 1/4.
• The result is 2/4.
• Simplify 2/4 to get 1/2.

Thus, two pieces of 1/4 equal 1/2.

To determine how many pieces of 1/5 are needed to make a whole, consider the following:

• A whole is equivalent to 1.
• Each piece is 1/5 of the whole.
• To find out how many 1/5 pieces make up a whole, divide 1 by 1/5.
• Dividing 1 by 1/5 is the same as multiplying 1 by 5.
• Thus, 5 pieces of 1/5 are needed to make a whole.

To compare the fractions, we look at their values:

• 1/2 is the largest, as it is the biggest fraction.
• 1/3 is next, as it is greater than 1/6 and 1/7.
• 1/6 comes after that.
• 1/7 is the smallest, as it has the largest denominator.

So, the fractions in order from greatest to least are: 1/2, 1/3, 1/6, 1/7.

John ate 2/4 of a pizza

Tom, Sarah, and Joane each ate 1/4 of a pizza, so together they ate 1/4 + 1/4 + 1/4 = 3/4 of a pizza

The total amount of pizza eaten is 2/4 + 3/4 = 5/4 of a pizza

They bought 2 pizzas, which is equivalent to 8/4 of a pizza

To find out how much pizza was left, we subtract the amount eaten from the total amount bought: 8/4 - 5/4 = 3/4 of a pizza

Since there are 12 cookies shared equally among 3 friends, each friend gets 12 ÷ 3 = 4 cookies. To find the fraction of the total cookies each friend gets, divide the number of cookies each friend receives by the total number of cookies: 4/12 = 1/3. Therefore, each friend gets 1/3 of the cookies.

One half of a whole is represented by the fraction 1/2. This means that if something is divided into two equal parts, each part is one half. 

When a square is divided into 4 equal parts, each part is called a quarter.

• A quarter is one of four equal divisions.
• This is similar to how a quarter represents 25% of a whole.

To find which fractions are equivalent to 1/2, we simplify each option:

• 3/6: Divide both the numerator and denominator by 3. This gives 1/2.
• 2/4: Divide both the numerator and denominator by 2. This also gives 1/2.

Therefore, both 3/6 and 2/4 are equivalent to 1/2. The answer is B: Both A and C.

When a cake is shared equally among three people:

• Each person receives one-third of the cake.
• This is represented as the fraction 1/3.
