Exe.1
show 5 possible solutions for each statement:
a) the sum of 2 decimals is less than 1
b) the sum of 2 decimals is equal than 1
c) the sum of 2 decimals is greater than 1

exe.2
the difference between two decimalsis 6.33. what might the two decimals be? show 5 different solutions.

exe.3
i multiplied two numbers and got a product smaller than both factors. what might the two numbers be?

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
