Question

On a 300 point standardized test, Luca earned 82% of the points. How many of the 300 points did Luca earn?

Answer 1

Answer:

1. He earned 246

82% = 0.82

Move decimal right twice

82 x 300 is 24600

Move decimal left twice

= 246

2. 25

Solve for Y (Total Diamonds)

12 = 48% × Y

12 = $\frac{48}{100}$ × Y

Y = 12 × $\frac{100}{48}$

Y = 12 × 100 ÷ 48

Y = 25

3.80.95%

Solve for "%"

% = 34/42

% = 0.8095 (rounded)

Convert decimal to percent using percent formula:

% = 0.8095 × 100 = 80.95%
