2. 146.25
explanation: find the decimal form of 325 (which is 3.25, just replace the % with a decimal point and then move it to the left 2 times), then multiply 3.25 by 45
3. 26
explanation: find the 10% of 130 (its 13, just remove the 0), then multiply 13 by 2 (which is 26)
4. 39 girls
explanation: (25x3 is 75 so just find the 25% of 52, which is 13, then multiply it by 3). Half (50%) of 52 is 26, and the half(25%) of 26 is 13, so 13 x 3 = 39
