The denominator is greater than one. The denominator is greater than the numerator. The difference between the denominator and the numerator is greater than the numerator. * 4. All the students in a class are sitting at tables.• There are 6 round tables, and 3 boys and 4 girls are sitting at each round table.• There are 7 square tables, and 5 boys and 3 girls are sitting at each square table.• Ms. Martin gives each student in the class 2 books.Which expression can be used to find the total number of books Ms. Martin gives to thestudents? 2 (6 + 3 + 4 + 7 + 5 + 3) 6 (3 + 4) + 7 (5 + 3) + 2 2 [6 (3 + 4) + 7 (5 + 3)] 6 [(3 + 4) + 2] + 7 [(5 + 3) + 2] * 5. Two sides of a polygon are parallel and have the same length. Which statement about thepolygon must be true? The polygon has exactly 3 sides. The polygon has exactly 4 sides. The polygon has at least 4 sides. The polygon has an even number of sides. * 6. Martha makes the statement shown below.When multiplying two whole numbers that end in zeros, the product always has the exact same number of zeros at the end as the number of zeros from the end of the two numbers combined. For example, the product of 80 × 400 has exactly three zeros at the end since 80 ends in onezero and 400 ends in twozeros. Which expression proves Martha’s statement is not correct? 10 × 100 20 × 200 30 × 400 40 × 500 * 7. A number has an 8 in the hundredths place. The number also contains a digit whose valueis 1/10 the value of the 8 in the hundredths place. Which could be the expanded form of thenumber? (1 × 100) + (8 × 0.1) + (8 × 0.01) + (2 × 0.001) (3 × 100) + (8 × 10) + (2 × 1) + (2 × 0.1) + (8 × 0.01) + (7 × 0.001) (8 × 100) + (8 × 10) + (1 × 0.1) + (7 × 0.01) + (9 × 0.001) (2 × 100) + (7 × 10) + (2 × 1) + (8 × 0.01) + (8 × 0.001) * 8. In the expression shown below, a and b represent different whole numbers.10 a × 10 b (a and b are EXPONENTS)How many zeros must be in the product of the expression? a + b a x b 2 100 Done
