Answer:

126

Step-by-step explanation:

(−3/10)(4.2)(−100)

=4.2[tex]*\frac{3*100}{10}[/tex]

=[tex]\frac{3*100}{10} =30[/tex]

=30 times 4.2 = 126

Answer:

126

Step-by-step explanation:

(−3/10)(4.2)(−100)

Since the product of -10 & 10 is -100, we can rewrite as-you may call this associative property I guess since I still haven't rearranged the factors:

(−3/10)(4.2)((−10)(10))

Associative property:

(-3/10)(4.2)(-10)(10)

Commutative property:

(-3/10)(-10)(4.2)(10)

Associative property:

((-3/10)(-10))((4.2)(10))

Simplifying:

(3)(42)

Simplifying:

126
