Answer:
-2 19/20, 2 3/5. 3.125, 10.35
Step-by-step explanation:
Let's solve each expression:
Solve:
-4.5 x -2.3
Multiply:
-4.5 x -2.3
10.35
Therefore, the simplified expression is 10.35
Solve:
5/-1.6
Divide:
5/-1.6
3.125
Therefore, the simplified expression is 3.125
Solve:
5 6/15 + (-2 4/5)
First, make the denominators of 4/5 equal to 15:
4/5 = ?/15
Multiply both the numerator and denominator by 3:
4 x 3 = 12
5 x 3 = 15
The new fraction is 12/15.
Add:
5 6/15 + (-2 12/15)
2 9/15
Simplify:
2 9/15 = 2 3/5
(divide the numerator and denominator by 3)
Therefore, the simplified expression is 2 and three-fifths.
Solve:
-3 3/10 - (-7/20)
First, make the denominators of 3/10 equal to 20:
3/10 = ?/20
Multiply both the numerator and denominator by 2:
3 x 2 = 6
10 x 3 = 20
The new fraction is 6/20.
Subtract:
-3 6/20 - (-7/20)
-2 19/20
Therefore, the simplified expression is negative 2 and nineteen-twentieths.
Order from least to greatest:
-2 19/20, 2 3/5. 3.125, 10.35
