4x + 600 = 7x 3x = 600 x = 600/3 = 200. So, there are 200 female members and 200 + 150 = 350 male members. Then, the total number of female and male members are - 200 + 350 = 550. Answer: C. 550 members Question 4: Step 1: We have the ratio - 3.25 to 1.30 Step 2: Then, we have - 3.25/1.30 = 325/130 (Multiplying the numerator and denominator by 100) 325/130 = 5/2. Answer: D. 5/2 Question 5: Step 1: The ratio of the number of ducks to the number of geese on Old MacDonald’s farm is 9:8. Say there are 9x and 8x ducks and geese. There are 68 ducks and geese on the farm. Step 2: Then, we have - 9x + 8x = 68 17x = 68 x = 4. Then, there are 9 * 4 = 36 ducks and 8 * 4 = 32 geese. So, there are 36 - 32 = 4 more ducks than geese.

Step 2: The ratio of the number of people who picked vanilla to the number of people who picked chocolate is - 30/40 = 3/4. Answer: C. 3 to 4 Question 7: Step 1: In the scale model of a dam, every 1/2 of a centimetre represents 1 kilometre of the real dam. The dam has a total volume of 216 cubic kilometres. The volume of scale factor is - (1/2)^3 = 1/8 Step 2: Then, the volume of scale model is - 1/8 * 216 = 27 cubic centimetres. Answer: D. 27 cubic centimetres Question 8: ©Scholarly 2025.
