Question

1. select the mathematical symbol that makes this number sentence true. 1.5

2
a

b
=
c
<

Explanation:

Step1: Compare 1.5 and 2

1.5 is less than 2, so the symbol should be '<'.

Step2: Identify the option with '<'

Looking at the options, option C (assuming the third option is '<') is the correct one. Wait, from the image, the third option has '∧'? Wait no, maybe a typo, but the correct symbol for 1.5 < 2. Wait the options: A is '>', B is '=', C is '<' (maybe the symbol is '<' as the third option). So we check 1.5 vs 2. 1.5 is less than 2, so the symbol is '<', which is option C (assuming the third option is '<').

Answer:

C. < (assuming the third option's symbol is '<' to represent "less than" as 1.5 < 2)
