7. If a person has 440 pens and 560 pencils, how many more pencils does he have than pens?

110

120

130

140

If a person has 560 pencils and 440 pens, they have 120 more pencils than pens. This is found by subtracting the number of pens from the number of pencils. In other words, if you took away all the pens from the total amount of writing instruments, you would be left with 120 pencils.

10. Which of these answer choices produces the biggest value?

450 - 78

12 x 12

700 - 301

258 + 107

The problem involves basic arithmetic calculations to find the largest value. First, subtract 78 from 450, which equals 372. Then, multiply 12 by 12 to get 144. Next, subtract 301 from 700, resulting in 399. Finally, add 258 and 107, which gives 365. Comparing all these values, 399 is the highest. So, the option "700 - 301" produces the biggest value among the given choices.
