ركعة‎ rakaʿah (pl. ركعات rakaʿāt) refers to one unit of Islamic prayer, or Salah. Each daily prayer is made up of a different number of raka'at:

* Fajr — The dawn prayer: 2 raka'at
* Shuhar — The noon prayer: 4 raka'at
* Asr — The afternoon prayer: 4 raka'at
* Maghrib — The sunset prayer: 3 raka'at
* Isha'a — The night prayer: 4 raka'at

The source of five prayers (as opposed to three) goes back to a disagreement in the Talmud. Rabbinic Jews connect "geulah" with "tefillah", meaning that the Shema prayer is said immediately preceding the Shemonah Esreh prayer. Arabian Jews under Sadducean (literalist) influences felt otherwise. The Shema prayer was commanded to be said when a person is actually rising and going to sleep. This instead of three prayers, they had five.

* Netz — The rising shema prayer
* Shacharit — The morning prayer
* Ashrei — The afternoon prayer
* Maariv — The evening prayer
* Shema — The bedtime shema prayer

Abu Isa following mystical custom included two more prayers. Chatzot HaLailah and Chatzot HaYom, midnight and midday prayers for a total of seven prayers. Even today there are Jews who follow this custom during the three weeks.

Salaam

There is a more information here

Basically the framework of Islamic prayer and Jewish prayer are both based on the format of prayer in the Temple in Jerusalem.

Jewish prayer has added many additional prayers over time, and takes about five times longer to recite.

Also, the qur'an explicitly refers to 3 prayers:

The other 2 prayers must have been innovations.
