Answer:

11\frac{13}{30}

Step-by-step explanation:

we have

7\frac{3}{10}+4\frac{2}{15}

step 1

Convert mixed number to an improper fraction

7\frac{3}{10}=7+\frac{3}{10}=\frac{7*10+3}{10}=\frac{73}{10}

4\frac{2}{15}=4+\frac{2}{15}=\frac{4*15+2}{15}=\frac{62}{15}

step 2

Adds the fractions

\frac{73}{10}+\frac{62}{15}=\frac{73*3+62*2}{30}=\frac{343}{30}

step 3

Convert to mixed number

\frac{343}{30}=\frac{330}{30}+\frac{13}{30}=11\frac{13}{30}

\text {Mass of earth =} 5.97 \times 10^{24} \text { kg}

\text {Mass of Venus =} 4.87 \times 10^{24} \text { kg}

\text {Difference = }5.97 \times 10^{24}  - 4.87 \times 10^{24}

\text {Difference = }(5.97 - 4.87) \times 10^{24}

\text {Difference = }1.1 \times 10^{24} \text { kg}


--------------- In Pure Text Format --------------
Mass of the earth = 5.97 x 10^{24} 
Mass of Venus = 4.87 x 10^{24}
Difference = (5.97 - 4.87) x 10^{24} = 1.1 x 10^{24} kg
