using comparative thinking which equations are true a.50+64=62+48 b.50+64=62+62 c.50+64=124+52 d.50+64=66+52
To determine which equation is true using comparative thinking, we need to compare the values on both sides of the equation. Let's analyze each equation:
a. 50 + 64 = 62 + 48
By adding the values on each side, we get 114 on the left side and 110 on the right side. Since these values are not equal (114 ≠ 110), this equation is not true.
b. 50 + 64 = 62 + 62
Similarly, adding the values on each side, we get 114 on the left and 124 on the right side. These values are not equal (114 ≠ 124), so this equation is also not true.
c. 50 + 64 = 124 + 52
Again, adding the values on each side results in 114 on the left and 176 on the right side. These values are not equal (114 ≠ 176), making this equation not true either.
d. 50 + 64 = 66 + 52
By adding the values on each side, we get 114 on both the left and the right side. Since these values are equal (114 = 114), this equation is true.
Thus, the correct equation is d. 50 + 64 = 66 + 52.
