Answer 3

Let's solve each of these equations step by step:

1. $4 \frac{3}{10} - 2 \frac{1}{30}$ To subtract mixed numbers, we need to convert them into improper fractions. $4 \frac{3}{10} = \frac{43}{10}$ and $2 \frac{1}{30} = \frac{61}{30}$ Now, subtract: $\frac{43}{10} - \frac{61}{30}$ To subtract fractions, we need a common denominator. In this case, the common denominator is 30: $\frac{43}{10} - \frac{61}{30} = \frac{129}{30} - \frac{61}{30} = \frac{68}{30}$ Now, simplify the fraction: $\frac{68}{30} = \frac{34}{15}$ Convert back to a mixed number: $\frac{34}{15} = 2 \frac{4}{15}$ So, $4 \frac{3}{10} - 2 \frac{1}{30} = 2 \frac{4}{15}$.

2. $1 \frac{5}{8} - \left(-\frac{5}{16}\right)$ We have a subtraction with a negative sign, which is the same as adding the opposite: $1 \frac{5}{8} + \frac{5}{16}$ To add mixed numbers, we need to convert them into improper fractions. $1 \frac{5}{8} = \frac{13}{8}$ and $-\frac{5}{16} = -\frac{5}{16}$ Now, add: $\frac{13}{8} + \left(-\frac{5}{16}\right)$ To add fractions, we need a common denominator. In this case, the common denominator is 16: $\frac{13}{8} + \left(-\frac{5}{16}\right) = \frac{26}{16} - \frac{5}{16} = \frac{21}{16}$ Convert back to a mixed number: $\frac{21}{16} = 1 \frac{5}{16}$ So, $1 \frac{5}{8} - \left(-\frac{5}{16}\right) = 1 \frac{5}{16}$.

3. $-59 - \left(-60\right)$ We have a subtraction with a negative sign, which is the same as adding the opposite: $-59 + 60 = 1$ So, $-59 - \left(-60\right) = 1$.

4. $-5.2 + 1.6$ Simply add the numbers: $-5.2 + 1.6 = -3.6$

5. $-7.2 + 0.8$ Simply add the numbers: $-7.2 + 0.8 = -6.4$

6. $-4.4 - 4.7$ Simply subtract the numbers: $-4.4 - 4.7 = -9.1$

Here are the results:

1. $4 \frac{3}{10} - 2 \frac{1}{30} = 2 \frac{4}{15}$
