Multiply 0.25 by 2 and you get 0.50
A system of equation is consistent if there is at least one solution. Since this system of equations has a single solution, it is consistent, the answer is true.
This problem is simply asking us to add the weights which are presented as fractions. You can easily get the answer if you input them directly in a calculator. But I think the challenge here is to manually add fractions.
Let's add the two 1/4 lb weights because it is easier for they have a common denominator. Just simply add the numerators.
1/4 + 1/4 = 2/4
Then, add with this the fraction part of 2 1/5.
2/4 + 1/5 = ?
The least common denominator is 4*5 = 20. Then divide 20 with each denominator and multiply to their respective numerator.
2/4 + 1/5 = [(20/4 * 2) + (20/5 *1)]/20 = 14/20
14/20 is simplified to 7/10. Then add the whole number 2. <em>Therefore, the sum of all weights is 2 7/10 pounds.</em>
Answer:
each bag weights 1,500 grams
Step-by-step explanation:
there are 1000 grams in a kilogram
6 times 1000 is 6000
6000 divided by 4 is 1500
