Explanation:

Question 4

Step1: Decompose 58

58 has 5 tens and 8 ones, so \( 58 = 50 + 8 \)

Step2: Decompose 27

27 has 2 tens and 7 ones, so \( 27 = 20 + 7 \)

Step1: Identify the minutes

Yesterday: 58 minutes, Today: 27 minutes

Step2: Add the minutes

To find the total, add 58 and 27: \( 58 + 27 = 85 \)

Step1: Identify the quantities

Red pens: 17, Red crayons: 35

Step2: Add the quantities

Add 17 and 35: \( 17 + 35 = 52 \)

Answer:

\( 58 = \boldsymbol{50} + \boldsymbol{8} \)
\( 27 = \boldsymbol{20} + \boldsymbol{7} \)
