Question 7, 27. Basis: The output of this province is less than that of last year, so the output of last year is reduced by10%: 30-30 *10% = 30-3 = 27 (ten thousand).

Question 8, 7.5. Basis: 10% discount refers to the percentage of the actual selling price to the original selling price, 10% means 10%, that is, 10%, and 80% means 20%. A 75% discount is a 7.5% discount.

Question 9. Correct judgment. Basis: Assimilate them into decimals and compare them. Your ideas and methods are correct.

10, 207 196.65. Basis: interest = principal * interest rate * maturity date = 5000 * 4.14% *1= 207 (where interest tax = interest * tax rate).

After tax interest = interest *( 1- interest tax) = 207 * (1-5%) =196.65.

The second big problem

Question 1 To be underlined. Basis: Percent is a number that indicates that one number is a percentage of another number, and cannot directly indicate the specific value, so it cannot indicate the length.

Question 2 should be ticked. Basis: It can be assumed that the number of sheep is 1, then the number of cattle is 2/5, and there are more sheep than cattle (1-2/5) = 3/5; That is, (3/5) ÷ (2/5) = 3 ÷ 2 =1.5 =150% of the cattle.
