The true number sentence is the third option:
6.8*1.3 = 8.84
Which number sentence is true?
Here we have number sentences of the form:
A*B = C
This is true only when the value of the product A*B is equal to the value of C.
One key thing to identify the correct one is remembering the rule of signs:
(+)*(-) = (-)
(+)*(+) = (+)
(-)*(+) = (-)
(-)*(-) = (+).
The only option that meets that rule is:
6.8*1.3 = 8.84
Where the product of two positive numbers gives another positive number (and the equality is true) so we conclude that this number sentence is true.
