According to my calculations, the LCM of the two denominators is 50. Therefore, since 50 goes into 50 a total of 1 times, you would multiply the top and bottom of the first fraction by 1. And since 1 goes into 50 a total of 50 times, you would multiply the top and bottom of the second fraction by 50. Now that the denominators are the same, you can simply compare the numerators to determine which fraction is greater. Since 21 is less than 2100, 21/50 is less than 2100/50. Therefore the 1st entry (21/50) is less than the 2nd entry (42).
Answer:
m=1
Step-by-step explanation:
tttttttttttttt tttt
you could use this equation to help you solve it;
x + (x + 42) = 138
the first step is to combine like terms;
2x = 138 -42
2x = 96
X = 96/2
X = 48
we already solved for x now substitute it in the equation I gave you.
48 + (48 + 42) = 138
48 + 90 = 138
hope it helped...if you have any concerns just let me know:)
