Examination paper of unit 5 of fifth grade mathematics 1. Fill in the blanks (1-4, 2 points each, 5 questions, 20 points each). 1 and the output in April is more than that in March. With () as the unit "1", the output in April is equivalent to that in March (). 2. If a person walks kilometers per hour, if he walks () kilometers, it is 1 hour, and the formula is (). 3, more than 4 kg is () kg, and more than () kg is 6 kg. 4. 10 meter is increased by () meter, and 10 meter is increased by () meter. 5.= () ÷ () = = 2. Choose (10 points) 1, the number of A is 60, the number of A is more than the number of B, and the number of B is (). A, 50 B, 48 C, 59 D, 300 2, 60 yuan after a pair of shoes is 20% off. This pair of shoes was originally () yuan. There are fewer boys than girls in grades A, 65 B, 72 C, 75th, 3rd and 6th, and boys are girls (). There are 20 girls in Class A, Class B, Class C, Class 4 and Class 5 (1), and many boys. Formula 20 ÷ (1+) is the number of students who want (). A, the number of boys b, the number of students in the class c, the number of girls is more than that of boys 5. A dress is raised first, then lowered. Compare the current price with the original price (). A, as much as B, C is higher than the original price, and 3 is lower than the original price. Calculate (30 points) 1 and directly write (9 points) ÷ = × 4 = ÷ =+× = 6-= 0 ÷ = × =+= 2 to solve the equation. For calculation outside the formula, the winner should be simplified (12) ×+⊙+(+-)× 2410 ÷+× 4. Look at the chart. The formula is (10) 1. Formula: Formula: 5. Solve the problem (30) 1. A garment factory produced 1500 sets of clothes in April, more than in March. How many sets of clothes were produced in March? Water becomes ice, and its volume increases. How many cubic decimeters should a piece of ice with a volume of 143 cubic decimeter become water? A toy factory produced a toy. It produced 800 pieces last month. This month, its output is less than last month. How many toys did it produce this month? 4. build a highway. If this road is built in the first week and in the second week, the task will be completed by repairing 14km. How many kilometers is this highway? 5.36 cars, more big cars than small cars. How many cars are there? 6. An engineering team built a highway, which has been repaired, leaving 2 10 meters. How long is this road? (column equation solution)
