the Highest common factor of 130,260,390 = 130
130 = 2⋅5⋅13
260 = 2⋅2⋅5⋅13
390 = 2⋅3⋅5⋅13
Common multipliers (130; 260; 390): 2, 5, 13
Now to find the highest Common factor you need to multiply the common factors
Answer: (130 ; 260 ; 390) = 2 ∙ 5 ∙ 13 = 130

Answer: 50
Step-by-step explanation:
Let the number of pizza made last week be represented by y.
From the question, we can form it into:
24% of y = 12
24/100 × y = 12
0.24 × y = 12
0.24y = 12
y = 12/0.24
y = 50
50 pizza were made last week.
Answer:
224 cubes
Step-by-step explanation:
1. Find the area: 2 * 1 *7/4 = <em>7/2 cm³</em>
2. Find how many cubes fit into 1 cm³: 4 * 4 * 4 = <em>64 cubes</em>.
3. Multiply the two numbers: 7/2 * 64 = 224 cubes.
