Question

1. 30% of \\(\square\\) is 48
2. \\(\square\\) is 40% of 35
3. \\(\square\\) is 80% of 45

Explanation:

Problem 9:

Step1: Let the number be \( x \). The equation is \( 0.3x = 48 \).

Step2: Solve for \( x \) by dividing both sides by \( 0.3 \): \( x=\frac{48}{0.3}=160 \).

Step1: Calculate \( 40\% \) of \( 35 \). Convert \( 40\% \) to decimal: \( 0.4 \).

Step2: Multiply \( 0.4 \) by \( 35 \): \( 0.4\times35 = 14 \).

Step1: Calculate \( 80\% \) of \( 45 \). Convert \( 80\% \) to decimal: \( 0.8 \).

Step2: Multiply \( 0.8 \) by \( 45 \): \( 0.8\times45 = 36 \).

Answer:

160
