Answer 1

1. 221+ 727

2. 45+5

3. 220+ 244

4. 2( -285)

5. (-9)

6. 1665 (multiplying)

7. -3074 (multiplying)

8. 685 *5

9. - 20 2/9

10. 82575 (multiplying)

Explanation:

1.34+914=____221_____________

948 = 221+ 727 (subtracting 221 from 948)

2. 16+34=______45___________

50= 45+5 ( adding 5 to 45 to get 50)

3. 46+418=_________220________

464= 220+ 244 ( subtracting 220 from 464)

4. 45-615=2 ________________

- 570 = 2( -285) (dividing -570 by 2)

5. 25-36=_________________ (-9)

-9 = -9 ( subtraction)

6. 37 x 45=_________________ 1665 (multiplying)

7. 58x (-53)=_________________ -3074 (multiplying)

8. 3425=_________________ 685 *5 (dividing by 5)

9. 910÷(-45)=_________________ 182/ (-9) (dividing both by 5)

= - 20 2/9

10. 367 x 225=_________________ 82575 (multiplying)
