Answer:
1. 11.891
2. 9.819
3. 101.153
4. 4.436
5. 15.3854
Explanation:
1. 'Take away' in the sentence means to subtract so we: 23.871 - 12.980 = 11.891
Note: 12.980 is the subtrahend while 23.871 is the minuend.
2. 12.341 - 6.543 = 5.798
12.341 - 8.320 (added 0 to make it more suitable to subtract) = 4.021
5.798 + 4.021 = 9.819
Note: We add zero to a decimal when the decimals are not equal to each other but that doesn't mean that the value of the decimal has increased, the decimal still has the same value.
3. 'Increase' in the sentence means to add so we: 98.277 + 2.876 = 101.153
4. 'Deduct' in the sentence means subtract so we: 10.097 - 5.661 = 4.436
Note: 5.661 is the subtrahend while 10.097 is the minuend.
5. 'The sum' in the sentence means to add or simply the answer of an
addition so we: 8.9600 (added two zeros to make the numbers equal) +
4.2120 (added 0 to make the numbers equal) + 2. 2134 = 15.3854
