Problem 1:

Mother bought 4/5 kg of fish and 7/10 kg of prawns. What is the total mass of seafood bought by mother in kg?

#### Step 1: Identify the fractions to add
We need to add:
$$
\frac{4}{5} + \frac{7}{10}
$$

#### Step 2: Find a common denominator
The denominators are 5 and 10. The least common denominator (LCD) is 10.

Convert $\frac{4}{5}$ to a fraction with denominator 10:
$$
\frac{4}{5} = \frac{4 \times 2}{5 \times 2} = \frac{8}{10}
$$

Now add:
$$
\frac{8}{10} + \frac{7}{10} = \frac{15}{10}
$$

#### Step 3: Simplify the result
$$
\frac{15}{10} = \frac{3}{2} = 1\frac{1}{2}
$$

#### ✔ Answer:
The total mass of seafood is $1\frac{1}{2}$ kg or 1.5 kg.

Problem 2:

Priscilla uses 3/8 kg of sugar to make biscuits and 1/2 kg of sugar to make cakes. Calculate the total mass of sugar used in kg.

#### Step 1: Identify the fractions to add
$$
\frac{3}{8} + \frac{1}{2}
$$

#### Step 2: Find a common denominator
Denominators are 8 and 2. The LCD is 8.

Convert $\frac{1}{2}$ to eighths:
$$
\frac{1}{2} = \frac{1 \times 4}{2 \times 4} = \frac{4}{8}
$$

Now add:
$$
\frac{3}{8} + \frac{4}{8} = \frac{7}{8}
$$

#### ✔ Answer:
The total mass of sugar used is $\frac{7}{8}$ kg.

✔ Final Answers:

1. Total seafood mass: $1\frac{1}{2}$ kg
2. Total sugar used: $\frac{7}{8}$ kg
